Genus Aptenodytes

Emperor Penguin - Its diet consists primarily of fish, but can also include crustaceans, such as krill, and cephalopods, such as squid. In hunting, the species can remain submerged up to 18 minutes, diving to a depth of 535 m . It has several adaptations to facilitate this, including an unusually structured hemoglobin to allow it to function at low oxygen levels, solid bones to reduce barotrauma, and the ability to reduce its metabolism and shut down non-essential organ functions.

King Penguin - King penguins eat small fish, mainly lanternfish, and squid and rely less than most Southern Ocean predators on krill and other crustaceans. On foraging trips they repeatedly dive to over 100 metres , often over 200 metres . Thus the King Penguin dives far deeper than any other penguin, notably excluding their closest relative, the larger Emperor Penguin.
